Contact : Marie-Christine GROMAIRE

Context

• Runoff from roadways and parking lots
• A complex matrix of micropollutants
• Need for source control / treatment
• Necessity to adapt the solutions to site specifics

Objectives

• Diagnose the composition and toxicity of runoff water, identifying primary sources
• Evaluate several innovative treatment solutions in situ in terms of efficiency (hydrology, chemistry and ecotoxicity) and sustainability (maintenance, aging)
• Analyse the overall environmental performance through a life cycle assessment (LCA)
• Assess solutions’ ownership conditions (social, technical and economic) and diffusion potential within the local context

Study sites

• 4 sites in Paris conurbation
• Contrasted pollution levels and urban contexts
• 4 treatment facilities
  • Both nature-based and technological devices
  • Vegetative filter strip and biofiltration swale
  • Pervious, vegetated car park
  • Small, horizontal sand filter
  • Compact settling / filtration / adsorption device

• Permeable filtering parking developped by Ecovégétal (Broué et Villeneuve le Roi)

  

• Non-infiltrating horizontal planted filters (CG93 – Rosny sous Bois)

  

• Vegetated shoulders + filtering / infiltrating ditches (CG77 – RD212 Compans)

  

• Compact decantation / filtration / adsorption device from STOPPOL 10CKF (Ville de Paris, voie George Pompidou)

  

Methodology

• A holistic and multidisciplinary approach
• Micropollutants studied
  • Diagnosis of road runoff contamination
    • Targeted screening: PBDE, DEHP, organotins, nickel, HBCDD, PFOS, benzotriazoles, tetrabromobisphenol A, platinoïdes
    • Non targeted screening
  • Performance evaluation of facilities
    • SS, POC, DOC, N, P, major ions, Hydrocarbons
    • Micropolluants: 12 metals, PAH, alkylphenols, bisphenolA, phtalates
    • Toxicity analysis

Tasks

• T1. Assessment methodologies of management systems
• T2. Monitor water composition and toxicity - Identify primary sources
• T3. Evaluate in-situ the effectiveness of several innovative treatment solutions of different technicalities (hydrology, chemistry and ecotox)
• T4. Analyze the global environmental performance (LCA) and the sustainability (maintenance, aging) of these solutions
• T5.Evaluate social and technical acceptability, cost, potential for diffusion of solutions
• T6. Valorisation and transfer of results
